DEVICE FOR TURNING MUSIC-LEAVES.

SPECIFICATION forming part of Letters Patent No. 685,262, dated October29, 1901.

Application filed March 30, 1901. Serial No. 53,720. (No model.)

To all whom it may concern:

Be it known that I, GEORGE OULLEY, a citi- Zen of the United States, anda resident of Cleveland, county of Ouyahoga,State of Ohio, have inventedcertain new and useful Improvement-s in Devices for Turning Music-Leaves, of which I hereby declare the following to be a full, clear, andexact description, such as will enable others skilled in the art towhich it appertains to make and use the same.

My invention relates to improvements in devices for turning the leavesof a music-book while lying upon the rack of an instrument ormusic-stand; and the objects of the inventionare to provide a device forthis purpose which will be readily accessible and by means of which aleaf can be turned without loss of time and with the minimum exertion offorce by the performer. I accomplish these objects by means of thespring-operated mechanism hereinafter described, shown in theaccompanying drawings, and specifically pointed out in the claims.

In the accompanying drawings, Figure 1 represents the device in positionupon a music-stand with the leaf-turning devices inserted between theleaves of a book placed upon the stand. Fig. 2 is a sectional View takenlongitudinally of the leaf-turning fingers and centrally through thespindles therefor. Fig. 3 is a detail view in section, showing themanner of attaching the fingers to their respective spindles and istaken on center line of spindles at right angles to Fig. 2. Fig.4 is aplan view of sectional gearing, and Fig. 5 is a detail of a modifiedform of finger constructed to retain a loose leaf in the music while itis being turned.

In the views, lis an inclosing case provided with any convenient meansfor attachment to the music-rack. In this case are mounted the spindles3, 4, 5, and 6, provided with short sleeves 7, to which the fingers 8are attached upon one side. These fingers are shown as wires bent to arectangular form and doubled back to give the fingers breadth. Theprojecting portion 9 engages the lower edge of the leaf, and thelongitudinal portion is inserted near the binding. The spindlesare'sleeved one over the other, thus giving to each the same center ofrevolution, and the fingers are attached tothe short sleeves ranged toengage an oppositely-placed segmental gear 11 upon the adjacent drum 12.These segmental gears are so placed as to successively engage theirseveral corresponding spur-gears one after the other, and thus operateeach finger in turn through one-half of a revolution, or sufficient toturn one page of the book. It will be seen that the lower gear and innerspindle rest directly upon the collar O, and each gear above or gear-hubrests upon the gear below. The short sleeves 7, secured to the upperextremities of the spindles, fasten them all in place.

The drum 12 is mounted upon the shaft 13, and a second drum 14:,provided with as many ratchet-teeth 15 as there are segmental gears, isalso placed upon the shaft. A handle 17 is employed to wind up thespring 16 upon the shaft 13. A dog 18 engages the ratchetteeth and ispivoted at 19 within the case. A spring 20 retains the dog in engagementwith the ratchet, and the spring 16 cannot operate to rotate thesegment-gears and the spindles until the dog is released by pressingupon the outer extremity of the lever at 21.

It .will be seen that a slight pressure upon the lever at 21 willrelease the spring, and one of the segments will engage with and rorateone of the gears until the dog engages the next tooth of the ratchet.Thus the operation of the device is perfectly under the control of theoperator, and the slight movement of the finger required to release theratchetdog will not be any great inconvenience to the performer orinterrupt his playing.

As many gears and segments may be employed as there are leaves to beturned, some compositions comprising a large number of pages, andsprings, as 30, may be made to rest against the gears to provide africtional resistance, so as to prevent more than one spindle frommoving at a time in case two or more should stick together.

In Fig. 5 a thin sheet of metal 40 is doubled ICG at 41, so as toinclose the edge of a loose leaf, which is apt to give great trouble tothe performer.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is

1. In a music-leaf-turning device, the combination with a suitable case,of a cylindrical standard therein mounted upon the lower side of thecase and projecting through the upper side, a collar upon said standard,spindles sleeved over said standard, one spindle being sleeved over theother, a gear upon the lower extremities of each spindle, the lower gearresting upon said collar and each gear hub or spindle extremity of theremaining gears resting upon the gear next below it, a sleeve secured tothe upper extremity of each spindle, a wire turner or finger for eachsleeve, said turner being looped at its upper extremity and having eachlower extremity secured upon one side of one of the sleeves, the saidsleeves increasing gradually in size and the said turners being bentabove their points of attachment to the sleeves so as not to interferewith one another in passing, substantially as described.

2. In combination, a case, a vertical standard mounted within said caseand projecting through one side thereof, a collar on said standard,hollow spindles sleeved one upon the other and the nest of spindlessleeved upon said standard and resting on said collar, a shortsleevesecured to the upper extremity of each spindle, awire turner securedupon one side of each short sleeve, and each turner bent at its base soas to pass the next adjacent turner, a gear secured to each spindle atits lower end, a drum adjacent to said standard, a drum-shaft parallelto said standard, a coiled spring and a ratchet-wheel upon said shaft, aspring-actuated dog arranged to engage said ratchet-wheel, segmentalgears upon said drum arranged to engage in turn said spindle-gears, anda handle upon said shaft, substantially as and for the purpose setforth.

3. In combination, a case, a vertical standard therein, a nest ofspindles sleeved upon said standard, a gear upon the lower extren1- ityof each spindle, a sleeve secured to the upper extremity of eachspindle, a wire leafturner secured to one side of each sleeve and bentto pass the next adjacent turner, a shaft parallel to the standard, adrum, a coiled spring and a ratchet-wheel upon said shaft, segmentalgears upon the drum arranged to engage in turn the gears upon thespindles, a spring-actuated dog arranged to engage said ratchet-wheeland provided with an extension beyond the case, and springs 30 securedto the case and arranged to engage the gears upon the spindles,substantially as and for the purpose described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

GEORGE CULLEY.
